Clip line segment defined by two points against plane. Region of Segment on positive side of Plane is kept.
FullyClipped if the segment lies fully behind or exactly in the plane FirstClipped if Point0 became the intersection point on the plane SecondClipped if Point1 became the intersection point on the plane NotClipped if the segment lies fully in front of the plane
